“Constitutional rights are something that are determined by the courts. But we wouldn’t be proceeding if we didn’t think believe we have the right and the responsibility under the Environmental Management Act to protect B.C.’s environment and coast against real threats,” Heyman said.

“I don’t think we are starting a constitutional crisis. I think we are proceeding with proposing regulations and consulting on relations to consult B.C.’s coastline and environment. That’s our job.”

Alberta Premier Rachel Notley is a staunch supporter of the Trans Mountain pipeline twinning project that would see a tripling in capacity of oil that can be moved from north of Edmonton to B.C.’s coast.

Notley sees B.C.’s actions as a threat to Canada’s constitution and a breach of interprovincial trade rules. She said her government will take any necessary legal action against B.C.

“Just because the B.C. government, in coalition with the Green Party, doesn’t like the decision gives them absolutely no right to ignore the law or… change the rules at half-time based on a whim,” Notley said.

Alberta is also threatening economic consequences. Notley said Alberta could refuse to take hydroelectricity from the Site C dam, which is currently under construction.

WATCH: B.C. is looking to limit bitumen flowing across its border and Alberta says that simply won’t stand. Alberta provincial affairs reporter Tom Vernon has more on the battle heating up between the two provinces over the Trans Mountain pipeline.

British Columbia is planning months of consultations with local governments, First Nations and other stakeholders to determine what sort of impact an oil spill could have on the environment.
